ULTRA WIDEBAND WIRELESS COMMUNICATION METHOD USING CHANNEL INFORMATION AND METHOD THEREOF, CONCERNED WITH CHANGING DATA TRANSMISSION METHOD IN TRANSMITTING PORTION ACCORDING TO ULTRA WIDEBAND CHANNEL STATE

摘要

PURPOSE: A UWB(Ultra Wideband) wireless communication method using channel information is provided to apply channel information obtained through a signal inputted from a receiver to a transmitter, so that the transmitter can change a data transmission method according to a UWB channel state, thereby selecting a transmission method according to a channel environment in a wireless channel. CONSTITUTION: A transmission module comprises as follows. A channel encoder(210) generates a bit stream by channel-coding digital data. A modulator(220) modulates the generated bit stream into a UWB signal. An RF module(400) wirelessly transmits the modulated UWB signal. A receiving module comprises as follows. The RF module(400) receives a wirelessly transmitted UWB signal. A demodulator(320) generates a bit stream by demodulating the UWB signal received from the RF module(400). A channel decoder(310) restores digital information from the bit stream. A controller(100) generates a control signal for the transmission and receiving modules, and properly operates a UWB wireless communication device according to a channel environment.
